I wouldn't take the chance and with the pan already off I'd certainly Plastigauge it. The Plasti gauge can be found at most parts stores and is cheap. Get some in the 0.001-0.003 range. The sleeve the plastic wire is in has the scale to read what the clearance is. Wipe journal and bearing clean, put a strip of Plasti gauge across the bearing, install and torque to spec, remove and hold the scale up to the flattened plastic. Do NOT turn crank and re-lube bearing before final install. Jerry was a teacher so he can give more lucid instructions I'm sure.
